The display of the iPhone XS Max is scientifically less harmful to our eyes

According to a study conducted by the Tsing-Hua University in Taiwan, the new OLED displays of the iPhone are significantly less damaging to our eyes than the old LCD screens. Here is what is the difference between the panels of the recent iPhone X and iPhone XS compared to the previous generation of iPhone.

Apple introduced the OLED displays on their smartphones for the first time last year with the iPhone X. Previously, LCD screens were used, optimized and perfected by Apple itself. This year Apple has continued to use OLED screens on the iPhone XS and iPhone XS Max but has reintroduced a new LCD screen called “Liquid Retina” on the iPhone XR.

According to the study mentioned above, the new iPhone XS Max has a coefficient of MPE (Maximum Permissible Exposure) 20% higher than the iPhone 7. This means that we can fix the screen of the iPhone XS Max for much longer before to feel a nuisance in the eyes. More precisely, the iPhone 7 causes a nuisance after only 288 seconds, while with the iPhone XS Max we can fix it for about 346 seconds despite the larger screen.

The iPhone 7 with its LCD panel also negatively affects sleep, compared to a more advanced screen like that of the iPhone XS Max. With a reduction of the blue light emitted from the OLED display, fix an iPhone XS screen before going to sleep is less harmful than an iPhone 7 display. The sensitivity to melatonin suppression is reduced from 24.6% of the iPhone 7 to 20.1% of the iPhone XS Max.

In a few weeks, it will be interesting to try out the new Liquid Retina screens of the iPhone XR, to see once again the real difference between an OLED panel and a very advanced LCD panel. Apple has probably managed to improve the technology of these screens, making them as similar as possible to OLEDs.
